Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by leveraging the Doctreat Core plugin's registration process. Since the vulnerable function, `doctreat_process_registration()`, does not properly validate user roles, an unauthenticated attacker can manipulate the registration to gain administrator privileges. This elevated access could then be used to compromise the entire WordPress site.
- Unauthenticated attackers can access registration.
- A registration function improperly allows admin roles.
- Leads to full site compromise via privilege escalation.
